#include <complex.h>

double complex conj(double complex z);
float complex conjf(float complex
z);
long double complex conjl(long double complex
z);

Link with −lm.

DESCRIPTION

The conj() function returns the complex conjugate value of z. That is the value obtained by changing the sign of the imaginary part.

One has:

cabs(z) = csqrt(z * conj(z))

VERSIONS

These functions first appeared in glibc in version 2.1.
